Unlike Europe, the Korean peninsula is still in the Cold War. For this reason the following paper on peace ethics, written by a Korean theologian and social ethicist, is highly relevant. Ahn Junggeun was a Korean independence activist, who was sentenced to death for assassinating Japanese Prime Minister Ito Hirobumi in 1909. In Korea and China he is revered as a resistance fighter against Japanese imperialism. But especially since the discovery of his Treatise of Peace in East Asia and his autobiography in the 1970s, both texts written in prison and unfinished, he is also regarded as a visionary for peace, international understanding and multilateral order. Ms. Dr. HyunJu Shim, senior researcher at the Institute for Life and Culture at the Sogang University in Seoul and member of our scientific advisory board has written an essay on Ahn Junggeun’s ideas and parallels with peace ethics in Catholic social teaching.
